Abstract
The structural member and fabrication thereof may be formed by mixing wood products chemically treated for durability and thermoplastics products. The fabrication process may included processing the products to a desired particle size; mixing the particles; processing the mixture in a high intensity processor and then processing the mixture in an extruder to obtain a molten state for forming the structural element in a mold. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a search or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
